More than 100,000 people packed the stadium where the Tennessee Titans play, to pray for repentance and the sins of the nation, organizers say.

The event was held on 7-7-07, as a symbol of seven being a covenant number in the Bible. Participants were challenged to repent and renew their covenant with God, while fasting and praying on the field.

The Call Nashville spokeswoman Julia Richardson said there was also music and prayer. The free event was designed to be more participatory worship than entertainment, she said.

The Call events began in 2000 with more than 400,000 people gathering on the National Mall in Washington, D.C. to fast, pray and worship God, according to event organizers.
